Speoiileation of Letters Patent.

Application tiled August 8, 1.913. Serial No. 783,723.

To all 'whom it may concern .f Be it known that we, WILLIAM SCnELLEN- BACH and WILLIAM Lonen, both citlzens of the 4United States, residing at Cincinnati, in the county of Hamilton, State o 0h10, have invented certain new and useful Improve-v ments in Multiple-Tool Holders, of which v the following is a specification.

Uur invention relates to a multiple-Way tool-holder.

The object of the invention is to lprovide an eflicient device of this nature, ,having conf venient provision for effectively clamping the tool-holder on its support; rotatably adjusting the holder relative to the toolholder support and column; adjusting the holder to predetermined positions; automatically latching and manually unlatching the holder relative to its operative positlons; these manipulations being preferably effected through the agency of a single lever.

The featuresof our invention Will be more fully set forth' in the description of the accompanying drawings, forming a part of this specification, in which Figure 1 is a central vertical section. Fig. 2 is a top plan view.l Fig. 3 is a section of a portion of the device on line w, fr, Fig. 1.

Fig. 4 is a bottom plan view of the latchV plate.

The tool post support 1, of a compound or simple rest, has the conventional T-slot 2. I provide a central supporting column 3, centrally bored longitudinally and formed With the foot 4, slipping endwise into the T-slot and holding said column against rotation. Column 3 is provided with the upper internal screw threads 5 and external threads 6. A bushing `7 surrounds the co1- umn and is supported upon the upper face 1. It is securely clamped in place by a nut 8, engaging threads 6.

The tool-holder 9 turns upon bushing 7 and column 3, and is to be clamped upon the upper face of the support 1, said holder having the vtool holding ways 10 .and ktool clamping bolts 11. Engaging threads 5, of column 3, is a counterbore clamp 12, vhaving an annular clamping surface 13, bearing 50 downwardly upon clamping ring 14, which rests upon' the upper face of the tool-holder 9. When member 12 is turnedV appropriafely the tool-holder Will be clamped between the ring 14, column 3, and support 1,

rotatably adusted The 4upper end of clamp 12 is tted to a socket piece` 15, the lever 16 being pivoted in one end of a slot 417, formed on the top of said socket piece,

the lever bridging the center hores of clamp 12 and column 3. Fitted into the bottom of tool-holder 9 is an annular latch-plate 18, lavng the pairs of diametrical slots arma,

s 0""61 latchplate turning with vthe tool-holder, to p resent the respective pairs'of slots in positions appropriately corresponding to the four ways of the tool support. A plunger 20 is inserted into the center bores of clamp 12 land column 3, which iS normally urged upwardly by spring 19, acting between the plunger head 26 and the` internal flange 2l of the clamp 12.

n the lower end of plunger 20 is a transverse latch bar 22, Secured thereto by nut 23, as shown in Fig. 3, and in section Fig. 1. The foot end of column 3 and bushing 7 are milled out, as shown in F ig. 3, for bar 22, and it is vertically guided by slots 24, in the bushing 7 and column 3. Y

Preferably the handle end of lever 16 is formed with socket 27 for engaging the heads of screws 11 for easily and conveniently rotating the tool-holder.

As shown in Fig. l, the tool-holder is unclamped and the plunger depressed to release latch-har 22 from engagement with latch-plate 18. The tool-holder may be then turned to bring a selected tool into operative position, the lever 16 will then be raised, the plunger rising to latch the tool-holder to'l cutting position, and by an appropriate turn of lever 16 in raised position, the clamp 12 will be operated to relatively clamp-lock togetherthe tool-holder, column and support into the position determined by the engagement of the latch-bar and plate.

Z-f1, downwardly facing, the

This multiple tool-way holder is efficient,

easily and conveniently operated, and is adapted to be applied to any conventional tool-holder support, particularly the compound Arest type wherein four-way toolholders are most commonly in requisition.

Having thus described our invention, we claim 1. In combination with a. support, a longitudinally bored supporting column non rotatably secured to said support, a. multi le tool-holder on the support, rotatable relatlve ay bp to the column, a center-bored clamp piece no screw-threaded to said column, means enabling the turn of said piece to relatively clamp together the support, column and toolholder, a latch-plate for the bottom of the tool-holder, a spring-plunger concentric.

with the clamp iece and column, having a llatch-bar norma ly engaging the latch-plate and interlocking therewith when in appropriate relative positions, a lever for vclamping and unclamping the tool-holder, rota- -ta'bly adjusting the support and operating the plunger. l

2. In combination with a support, a longitudinally bored supporting column noni'otatably secured to said support, a multiple tool-holder on the support rotatable relative to the column, a latch-plate between the support and tool-holder, movable with the latter, a counter-bored clamp piece screwthreaded to the colunm and formed witha transverse slotted head, a lever pivoted in the slot of the clamp piece and bridging.

the center bore, means whereby the rotation of said clamp piece clamps or unclamps Vrelatively the support, column and toolholder together, a spring-plunger passing through said clamp piece `and column, a latch-bar on-the lower end of the plunger coperating with the latch-plate, said bar being vertlcally guided in the walls of the lower end of the column, the upper end of the plunger .being engageable by the lever to effect the unlatch'ing, the spring automatically effecting the latching operation when the latch-plate is presented to the'latch-bar in positionsl corresponding to operative tool positions of the holder, and means for securing tools to said holder.v

3. In combination with a support, a column non-rotatably secured thereto, a multiple tool-holder rotatable on the column and support, means for relativel clamping the support, column and tool-ho der means automatically latchng the tool-holder in predeterminedl positions on the support, adapted to be manually unlatched, and a lever rotatably movable., in transverse planes for actuatin the clamp and latch, and for rotatably adjustingthe tool holder.

4. In combination with a support a longitudinally bored column non-rotatably xed to the support, a multiple -tool-holder'rotatable on the column and support, a centerbored clamp member screw-threaded on the column, .a slotted head for said member, a

lever pivoted therein and bridging the bores of the column and clamp member, the handle end of said lever when lying in the slot being adapted to engage the tool-holder to 'rotatably adjust the same, means whereby an appropriate turn of said member relatively clamps together said support, column and tool-holder, a latch-plate on the toolholder, a spring-plungerl within the clamp member and column,I a latch-bar on said plunger coperating with said latch-plate, said bar being vertically guided in the column, the plunger head projecting normally into the slot of the clamp member, and means for securing tools to said holder, the lever manipulations controlling the clamping, swiveling and latching operations.

5. In combination with a support, a Xed column thereon, a multiple tool-holder rotatively adjustable on the column and support, means for relatively clamping the'support, column and tool-holder, means autoj matically latchng the tool-holder in predetermined positions on the support, a lever adapted'when raised to actuate said clamp and latch, and when depressed to release the clamp, unlatch the tool-holder and engage a portion thereof for adjustin the same, and means normally holding sai lever 1n latching position.

6. In combination with a support, a xed column thereon, a multiple tool-holder rota tively adjustable on the column and support, means for relatively clamping the support, columnA and tool-holder, spring actuated means automatically latching the tool-holder in predetermined positions on the support, a lever adapted when raised, to actuate said clamp and latch, and when depressedto release said clamp and latch, and engage a portion of the tool-holder for adjusting the same, the latch spring mechanism normallly holding the lever in position with the too holder late-hed to the support.

In testimony whereof, we have' hereunto set our hands.
